in typewriters, and relates, more especially,

to novel features in the type-bar guide and the ribbon-viln'ator.

In typewriters as heretofore constructed, it has been deemed essentialthat the typebar guide he either rigidly supported in position or bemovable for a slight distance to expose the writing line. In thesemachines,

however, the platen carriage was not re-l movable unless the certainparts of the mai chine be removed to permit the platen carriage to betaken oil. In the type of machine herein illustrated., the platencarriage is removable without necessitating any dismantling of themachine, and a machine of this construction I have described and claimedin my pending application. led July 11, 1911, Serial blo. 637,900. Itmay be stated, generally speaking, that the main object of removing theplaten carriage, as specified, is to enable the machine -to be tatingtransportation and handling by the user. I

In a machine of the ordinary type of the prior art. -if the carriagewere removed, even by dismantling certain' parts thereof, the

type-bar guide and ribbon vibrator would Lio' project upwardly from thebody of the machine, thereby precluding packing the machine compactly,but, also, exposing such parts to injury. I

The present invention overcomes thedisadvantages specified. and. withthese objects in view, embodies a pivoted type-bar guide whereby saidguide may he rotated out of its normal upright position.

rl'he invention embodies, further, a ribbon vibrator adapted to besimilarly rotated ont of its normal position, and. in the preferred formof this particular embodiment of the invention. I associatethe vibratorwith the type-bar guide. so that the latter serves xas the support forsaid vibrator, and guides its movement.

advantages thereof, will appear from the annexed detailed description.

In the accompanying drawings, I have illustrated one practicalembodiment of the invention, but the construction shown there- '1n is tobe understood as illustrative, only, and notas defining the limits ofthe invention.

Figure 1 is a vertical transverse section through a part of a typewriterillustrating the new type-bar guide and ribbon-vibrator 1n operativerelation to the platen carriage, the dotted lines illustrating the saidguide and the ribbon-vibrator adjusted to inop- Fig. 2 is a verticalsection on an enlarged scale through the guide and the vibrator,illustrating a part of the platen carriage. Fig. 3 is a horizontalsection on an enlarged scale through the guide Fig. i is a perspectiveview of the guide and the vibrator det-ached from the machine.

5 is the platen carriage of a typewriter. s shown, this carriage issupported for sliding movement upon a bed plate (i, the latter beingadapted for vertical movement with respect to the type bars T. rTheworking parts of the typewriter are carried by a suitable frame 8, thesame embodying a sector 9 to which the type. bars are hung, each typebar being actuated by a suitable key lever 10. The foregoing parts areusual in typewriters of the so-called front strike type, and certainfeatures of such a machine, more particularly a removable platen.carriage and operating mechanism therefor` are disclosed in my priorapplication to which reference has been made.

11 is a horizontal supporting bar, the same being pivotally mounted inbearings 12 on the machine frame, whereby said bar is mounted forrocking or turning movement. This bar carries a member'l forming theguide for the type bars 7. The bar and the. guide are positioned on theframe in front of the platen carriage, and 4parallel to the guides forsaid carriage, said guide 13 being arranged at the middle part of theframe heads on the type bars j iIhe guide '1B is shown as consisting ofa single plate, one end of which is formed into a head 14. The endportion of the plate and the head thereof are slotted-at 15, and theedges of the slotted head are bevso as to lie lin the path of the type ylOl eled at 16, whereby the head end of'l the i guide is forked rorbifurcated.' The plate of said guide 13 vis attached rigidly in asuitableway to the supporting bar, so that the guide isrigid with thebar.

17 designates the ribbon-vibrator, the

same beingslidably fitted to the guide so as to be supported thereby`and movable there'- with. The vibrator is shown as a plate provided; atone endl with a series of fingers 18, 19, 20,' 21,. said platebeingprovided,

f also, with clips 22. 4The vibrator plate is 'seated against the lowerend portion of the --fitted in compact relation to the type-bar guide,and the vclips of' said v.vibrator 1 embrace the side edges of theguide, so that the clips operate 'to retain'the vibrator in positionupon the guide, whiley at the same' vtime Athe clips permit the vibratorto slide upon vthe guide. ,The lingers 19, 2O of the vibrator larepositioned at 'the respective sides of the slot 15 in the guide head,and these fingers are substantially out of alinement with the otherlingers 18, 21, oi' the vibrator. Said fingers 18, 21, are provided attheir upper ends with fianges 23, theV latter' overhanging the path of ayribbon (not shown), said ribbon being free to pass through the spacesseparating the fingers 18, 19, and 20, 21, and beneath the flanges 23.The slidable vibrator is provided with a depending stem 24, around whichis coiled a spring 25, one' end .of said spring beingl type-bar guide13. The stem is provided at its lower end with a head 26, upon whlch isseated the lower end of spring 25, and thls head is positioned forfrictional contact by the bar, and the vibrator is depressed by thespring so that the ribbon will occupy a low position relative '.to theslot in the guide, thereby exposing the writlng l1ne on the platen. Uponthe depression of a key,

the type bar is thrown upwardly in the usual way and themember 27 islifted for the purpose of raising the vibrator and the ribbon, thespring being compressed. The head of "the type bar is thus caused topass through the slot in the type-bar guide, the latter acting toposition the type head accurately with respect to the writing line, thuspre serving the alinement. The upward movement of the actuator lifts theribbon `into the path ofthe type head, but'as the type bar falls back,the spring acts promptly to lower the ribbon relative to the fork inthetype-bar guide.

In the normal operative. relation yof the type-bar guide and the ribbonvibrator tc the platen carriage, said guideand vibrato] extend upwardlyfrom the" rockable supporting bar, as a result ,of which' arrangementsaid guide or the vibrator, or both'oi vthese parts, are in the pathofsome ofthe 1into the out of service position-shown in dotted lines inFig. 1, the supporting bar turning on the 'bearings afforded by .thebrackets vof the frame, thus disposing -vthe vibrator and the'guide intoa'n out -of the way or out of service position, so that the carriage canbe removedwithoutstriking against the guide or the vibrator. Anotheradvantage secured by turning the guide and the vibrator into the out ofservice position upon remoyalof the platen carriage is that the guideand the vibrator,I occupy a compact relation to the other parts of themachine, so that they are not likely to be struck and injured whenpacking vthe machine or in transporting and shipping it.A 1When adjustedas described.l the head of the stem `rides against the curved .member 27so as lto compress the spring, the tension of which acts to retain theparts lin their adjusted positions. To return the parts again tooperative positions, itis necessary only to lift the guide and vibratorto the full line position of Fig. 1, whereupon the tension of the springis relaxed somewhat, although the spring is still somewhat under tensionso that it will act to hold the supporting vbar from turningaccidentally.

l-have not considered it necessary to fully illustrate or describe theribbon mechanism, or other parts of theI machine, for the reason thatsaid mechanism and parts are not of the present invention.

' Having thus fully described the inven tion, whatl I claim as new, anddesire to secure by Letters Patent 1s:-
